Thermostat, power, gas supply, ignition and control-board testing to find why the furnace will not fire.
Furnaces that click, light and shut off are often a dirty flame sensor or a failing hot-surface igniter.
Limit switches, pressure switches and inducer motors checked in order.
Overheating from restricted airflow, a dirty filter or an oversized furnace.
Banging, squealing or a burning smell checked before the next cold night.
Venting, heat-exchanger visual check and carbon monoxide concerns raised in plain language.
Clayton winter nights can drop below freezing, and the city has recorded lows near 15 degrees. Many homes still heat with the gas furnace installed when the tract was built.
Failed igniters, dirty flame sensors, pressure switch faults and blower motors are the most common causes. Each is checked so only the failed part is replaced.
HAXX checks venting, the heat exchanger and combustion before returning a gas furnace to service.
BAAQMD's zero-NOx rule for gas furnaces applies to sales of new units from 2029, not to repairing the furnace you have.

Common causes are a dirty flame sensor, a blocked vent, a failing pressure switch or an overheating limit. HAXX finds the cause before swapping parts.
No. The rule covers new units sold from 2029. Fixing the furnace already in your Clayton home falls outside it.
If the furnace is old or the repair is expensive, it is worth pricing a heat pump, which also adds cooling. HAXX can quote both.
No. Turn it off, leave the house if the smell is strong, and call PG&E or 911. Call HAXX for the repair once the area is safe.
